Whole-house filters: brands compared on published prices

Brands with evidenced Whole-house filters products

A brand appears here when its own live product or collection page for Whole-house filters answered at the linked URL on the date shown. Prices in the table are each brand's advertised prices for its named systems; shipping, installation and local water conditions change the delivered cost.

Choosing a whole-house filter

Tank-based systems and cartridge systems split this category: tanks cost more up front and run years between media changes, cartridges start cheaper and ask for regular filter spends. Price the system plus a decade of consumables, not the checkout number; both figures come from the same linked product pages.

Flow rate is the sizing axis buyers miss: a system rated below the household's peak demand throttles showers when appliances run. The brands print gallons-per-minute ratings beside their prices, and matching that number to your home matters more than any brand-versus-brand debate.

Common questions

What is the best whole house water filter?

For city water, a carbon system sized to your peak flow from a brand whose media certifications you have read; for specific contaminants, the system whose linked page names your contaminant. The verified prices below make the shortlist honest.

Do I need a whole house filter and a softener?

They fix different things: filtration handles chlorine, sediment and contaminants, softening handles scale. City-water homes with hard water commonly run both, and most brands below sell the pair as a combo on the linked pages.
